HOT-WATER STOVE.

Application filed August 18, 1924. Serial No. 732,623.

To all whom it may concern:

Be it known that I, SAMUEL V, REEVES,

a citizen of the United States, residing at I-Iaddonfield, county of Camden, State of .5 New Jersey, have invented a new and useful HOt-VVater Stove, of which the following is a specification. V

In a copending application, I have de scribed and broadly claimed a novel hot in water stove for multiple heating systems wherein a plurality of superimposed water chambers with a separate source of heat for each water chamber are employed.

. My present invention comprehendsanovel 15 hot waterstove of the same general character and enables one to obtain more efficient results.

In devices of this character, it is desirable to utilize one water chamber as a source so of hot water supply for the radiators, and to use a separate and independent water chamber as a source of hot water supply for household purposes, such as for the kitchen and the bath room.

In accordance with my invention, a single fire can be used to heat both water chambers. In the summer time when the radiators are not used, only the top fire is employed.

My invention further comprehends a novel hot water stove wherein the draft for combustion of'the upper fire is independently controlled.

It further comprehends a novel hot water stove in which a preheater is permanently connected with the upper water chamber.

It further comprehends novel insulating means for the water jacketed fire pot and for the preheater.

It further comprehends a novel hot water stove having superimposed fires wherein the upper fire can be used for various purposes such as ironing, frying, pot roasting and other cooking without interference with the maintainance of a checked fire below the upper fire.

'Other novel features of construction and advantage will hereinafter more clearly appear in the detailed description'and the appended claims.

For the purposes of illustrating the invention, I have shown in the accompanying drawing a typical embodiment of it, which, in practice, will give reliable and satisfac' y r sults. It is, howe e to be under stood that this embodiment is typical only and that the various instrumentalities of which my invention consists can be variously arranged and organized, and that the invention is not limited to the precise arrangement and organization of these instrumentalities as herein set forth.

Referring to the drawings:

1 designates the base of a hot water stove, embodying my invention. A base top or ash pit ring 2 may, if desired, be mounted on the base 1 and is flanged at the top to receive the preheater 3 which if the ash pit ring is not used would be supported on the flanged top of the base 1. The preheater is in the form of a ring shaped casting having a water chamber at to. which the cool or cold water is admitted by the conduit 5 from the boiler 6. The preheater 3 has inwardly projecting bosses 7 .to support a grate rest 8 which carries the grate 9 which receives the pin 10, and the grate handle 11 extends exteriorly of the stove. The preheater 3 has the spacing ribs 12 to which reference w1ll hereinafter be made.

The preheaterB is recessed at its upper end as at 13 to receive the lower end of the cored or Water acketed fire pot 1,4, the water chamber 15 of which is preferably of greatest diameter intermediate its ends.

The fire pot 14: carries at its upper end a draft ring 16 having at its bottom an outwardly extending flange l7, and this ring is provided with a desired number of air inlet holes 18 which are controlled by a slide ring 19 having a grasping handle 20 and provided with airinlet holes 21, see Figure 2, which correspond in number with the number of air inlet holes 18 with which latter it can be brought into the desired communication in accordance with the draft desired. 22 desi nates in upper cored or water jacketed fire pot having a water chamber 23, the lower portion of which is permanently connected by a conduit 24 with the upper portion of the water chamber 4 of the preheater 3. The upper fire pct 22 has at its lower portion the inwardly projecting lugs or bosses 25 which support the upper grate rest 26 on which is rotatably mounted the upper grate 27. The grate 27 has a shaking handle 28, see Figure 4, which extends through the opening 29 and through the curved plate 30 which covers said opening 29 and moves in unison with the upper grate. The grate 27 has a removable section 31 and when this is removed the size of the upper fire can be reduced by the insertion of the vertical grate section 32, having lugs to enter holes in the grate.

The upper water jacket 22 carries a top casing ring 33 which in turn carries the top 34 which is provided with one or more removable lids 35. The exit fiue 36 is provided with a manually controlled damper 37. The upper portion of the water chamber 23 of the upper fire pot 22 communicates by means of a conduit 38 with the boiler 6 or with the hot water pipe 39 leading therefrom the water chamber 15 of the fire pct 14 is provided with an inlet pipe 40 and with an outlet bipe 41, which latter forms the feed line to the radiators, while the pipe 40 forms av part of the return line from the radiators.

In case the upper fire only is to be employed, I preferably use an insulating thimble 42 having an upper flange to which are pivoted the angle brackets 43, as at 44, so that they can be moved outwardly to be supported upon the upper end of the fire pot 14, and provision is made for locking them in such position by means of the ap: ertures 45 in the flange and in the angle brackets, and a pin 46 is provided which looks them in position, see more particularly Figure 5. I

It will be seen that the thimble proper 42 comprises a sleeve connected at its upper end to flange ring 47. In some cases too much hot water is provided by the preheater, and, in such cases, an'insulator ring 48 having the laterally projecting lugs 49 is employed, the lugs restingon top of the It will of course be apparent that the fire pot in cross section may have any desired contour and in Figure 8, T have shown a section taken above the upper fire to illustrate a damper control for the air for combustion for the upper fire when the stove is rectangular in cross section. In order to provide the necessary draft for combustion I employ one or more air inlets 50, which are controlled by manually actuated slide dampers 51, and, as illustrated, an air inlet with its slide damper is shown at the front and also at one side of the upper fire pot. The air inlets are in the casting 52 which corresponds to the member 16, seen in Figures 1, 3 and 7.

The operation will now be apparent to those skilled in this art and is as follows:

In my copending application to which I have hereinbefore referred, the draft for combustion of the upper fire was derived from the source of draft supplied for the lower fire. In my present invention the provision of an independent draft supply for the upper fire makes it possible to operate the upper fire when the lower fire pot con tains a considerable accumulation of ashes or under conditions when the lower fire is burning slowly and checked. In the spring and in the fall of the year when but little heat is desired a sufficient quantity of hot water for the bath and kitchen is not ob tained. At such times, with the lower fire checked, the upper fire may be operated to its full capacity, or in a reduced form by re moving the small front section 31 and inserting the upright front section 321 The heat thus supplied from the upper fire pot will provide the required amount of bath and kitchen water while the lower fire pot and its water circuit is supplying the required heat for the radiators or heating system. 7

This top fire'method renders it possible to utilize the upper fire for various household purposes such as for example, ironing, cooking, and especially for frying, pot roasting or other cooking operations which produce obnoxious odors.

In the cold season when the radiator system is being heated by the main-lower fire, it is not necessary to employ the upper fire.

In order to insure the necessary supply of bath and kitchen hot water in mild winter weather when the volume of the lower fire is less than normal, I provide a preheater ring or circuit, which can be placed either on the ash ring or on top of the base. The cool or cold water from the lower portion of the boiler enters the preheater' through the conduit 5, and makes a complete circuit before passing out through the conduit 24 to the upper water chamber 23. This preheater ring insures'an abundance of hot water at all times when the lower fire is a source of hotwater supply for the bath and kitchen hot water circuit. It also increases the volume of bath and kitchen water when the two fires are used at the same time-for example, in the spring and in the fall of the year. A heavy cast iron ring can be placed inside the preheater and spaced by the ribs 12 from the inner wall thereof to reduce the supply of hot water, and, if desired, this can be provided with the openings 53 which may be of any desired dimensions so that any desired proportion of the hot water capacity of the preheater 3 may be employed. For example, if, it is desired to reduce the supply of hot water one-third, an insulating ring is employed which will cover substantially onethird of the fire contacting surface of the preheater.

When the radiators are not in use as in the summer time and only the upper fire pot 22 is employed, the insulating thimble 42 is inserted into the upper end of the fire pot 14 and the angle brackets 43 are turned so thatfthey will be supported upon such fire pot. They are then locked in position by inserting a nail, cotter pins or equivalent fastening devices which pass through the apertures 45 so that when the grates are being shaken or the stove vibrated from any cause this insulating thimble will be retained in proper place. This thimble prevents the heat from the lower portion of the upper fire heating the water in the water chamber 15 of the lower fire pot 14. The usual type of adjustable draft door 54, see Figure 3, is employed for the lower fire, so that each fire has its independent draft which is independently controlled. The number of air inlets is determined by the size of the air rings or their equivalents, and the size and volume of the fires.

Any desired type of grates may be employed, and, in practice, both the revolving grates and the draw bar types of grates are employed.

It will be apparent from the foregoing, that, in accordance with my present invention, I have devised a hot water stove for multiple hot water heating systems which after once being installed, can be readily adjusted and operated by the householder to provide the desired amount of hot water for the radiator, for kitchen and bath purposes or for all of these purposes in accordance with varying climatic conditions.

There is much less likelihood of the water for the bath and kitchen purposes becoming discolored if a separate hot water heating circuit is employed, as herein disclosed, as the main discoloration of the water is derived from the radiator circuit, which, in accordance with my invention, is entirely distinct and separate from the water circuit which provides the hot water for bath and kitchen purpose.

\Vhen both fires are used, the insulating thi ble 4 i rem ed he nsula g mmbers and the grate'scan be removed through the top of the stove without dismantling the stove. It will be seen that the inner wall of the preheater forms a continuation of the inner wall of the iire pot 14, and the internal diameter of the upper fire pot 22 may be equal to or less than that of the fire pot 14.

It will be apparent that the draft door 54 is controlled in the usual manner, and by rotating the slide valve 19,'its openings 21 will provide any desired air inlet opei'iings of the openings 18, so that the upper fire can be run at any desired capacity.

If the upright grate 32 is in place and the grate section 31 is removed the fuel for the lower fire can be fed through such opening formed by the removal of the section 31, and a poker can be inserted if it is desired to stir the lower fire without shaking its grate.

If desired the. preheater can be used dry,

in which case, of course, no hot water will be obtained from the upper water chamber 23. If the preheater is to be used dry, an insulating member is inserted which is constructed to completely cover the fire contacting surface of the preheater in order to prevent the cracking of the walls of its water chamber. It will, of course, be apparent to those skilled in the art that for convenience of illustration I have shown the conduit 24 at the side opposite to the conduit 5 and the conduit 38, but in practice it is placed on the same side and the water chambers 4, 15 and 23 are provided with a partition in the usual'manner which separates the inlet sides from the outlet sides of such chambers.

It will now be apparent that I have devised a new and useful hot water stove which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described a preferred embodiment thereof which will give in practice satisfactory and reliable results, it is to be understood that this embodiment is susceptible of modification in various particulars without de parting from the spirit or scope of the invention or sacrificing any of its advantages.
